WATER-TAN K.

SPECIFICATION forming part of Letters Patent No. 460,998, dated October 13,1891. Application filed March 7, 1891. Serial No. 384,164. (No model.)

one inch wide and one-fourth to one-half inch deep, as shown in Figs. 3 and t at e. They are set up on the foundation, and held in position by metal bands or hoops of any desir able Jform and width, the ends of the hoops being rounded for six to eight inches from the ends and threaded and litted with nuts and washers.

The wooden lug c, Fig. 3,is a piece of hard wood of equal length with the staves and two by four inches in size, and iitted with holes bored through it in the direction ot the ends ot the hoops-two holes for each band-as shown in Fig. 2. The bandsare passed through the lug and nuts screwed up till the staves are drawn tightly together.

The bottom b is construct-ed by laying two to four inches of cement, made by mixing `two parts Louisville cement and two parts clean sand, or by mixing two parts Portland cement and three parts sand, on the foundation, as shown in Fig. 5, and inside of the tank, lthe parts nearest the staves being curved upward so as to meet the staves three to tive inches from the bottom and worked into the chamter, as shown in Fig. l.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, in a water-tank, of wooden staves grooved out near the bottom on the inside and having a cement bottom extending above the groove, with a single lug` c extending up the outside and the vertical height ot the tank, tted with holes through which the ends of metal bands d are fastened, all substantially as described.

2. The combination, in a water-tank, of staves, a lug c, arranged lengthwise of said staves and having a series ot holes therein, and a series ot hoops surrounding the tank and having their ends secured in the holes in said lug, substantially as and for the purpose To a/ZZ whom it may concern:

Be it known that I, JOHN A. SPEER, residing at Cedar Falls, in the county of Black Hawk and State of Iowa, have invented a new and useful Vater-Tank, (which has not been patented in the United States nor in any foreign country,) of which the following is a specification.

My invention relates to improvements in l water-tanks, in which vertical staves are bound together by metal bands, the ends of which pass through a vertical woo den lug ex tending to the vertical height of the tank, and in which the bottom of the tank is made l of cement. The objects ot my invention are, l first, to provide a rigid, substantial lug, which is easily7 put in place and which prevents the hoops or bands from falling out of place if slackened by shrinkageof the tank; second, to provide a bottom for water-tanks which is at once rigid, non-shrinking, impervious to water, and not subject to decay. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 'l is a cross-section of the tank, tilted back so as to show the edge and under side of the cement bottom. Fig. 2 is a View of an entire tank, showing position of wooden lug and metal band. Fig. 3 is a view of inner side of tank stave, showing chainfer. Fig. et is a view of edge oit stave. Fig. 5 is a view of base on which cementbottom is laid,show ing a cross-section of same and of tank standi ing thereon.

Similar letters refer to similar parts through out the several views.

rhe `foundation for the tank shown in Fig. 5 is constructed by excavating t-o the depth of six to eight inches in the earth a space a few inches larger than the base of tank. The excavation may be filled with stone, brick, gravel, or other suitable material, or the foundation may be constructed ot'plank, on or above the surface of the earth. setforth.

The staves are made of any desirable material and length, beveled on the edges in JOHN A' SPEER" form to make a tank ot the size desired, and \Vitnesses:

are chamfered out at two inches from the ALFRED GRUNDY,
